We are using easyRDF to convert the RDF output file to a php file that displays the graph of the data. RDF is meant to be easy to interpret for computers and not humans, therefore it takes some time getting used to setting up the structure of the information correctly. Though when set up correctly it makes it quite easy to split up the information into categories and thus access to specific areas pretty straight forward.
